Window



.F. L MARSHALL WINDOW June 10, 1941.

-F' iled Aug. 5, 1939 Patented June 10, 1941 UNITED STATES PATENT OFFIQE 4 Claims.

This invention relates to an improvement in windows, more particularly in weather strips for windows of the sliding sash type, and has as its primary object the provision of a parting strip of yielding construction which serves to guide the sashes, to hold them yieldably against rattling, and to prevent the entry of wind, dust and the like past the ends of the sashes.

A further object of this invention is to provide a parting strip which can be easily mounted in or removed from the vertical groove usually provided in the window frame and which can be substituted for usual wooden parting strips.

These as well as other objects of this invention which reside in the various features of construction incorporated in a parting strip embodying this invention will be apparent from a consideration of the following description of this invention and of the accompanying drawing which forms a part thereof, and in which- Fig. 1 is an isometric view of a portion of a window illustrating the structure of a parting strip embodying this invention and the relation of such parting strip to the window sashes and frame;

Fig. 2 is a longitudinal cross-sectional view of such window;

Fig. 3 is a perspective view of the parting strip showing the various elements thereof. partially separated for the purpose of clarity;

Fig. 4 is a cross-sectional view illustrating the insertion or removal of the parting strip from the window frame;

Fig. 5 is a view similar to Fig. 4 with the parting strip seated in the frame; and

Fig. 6 is a View similar to Fig. 3, of one section of parting strip.

In the drawing is shown a window assembly comprising a side rail I0, sashes II and I2, outside guide beads I3 and I4, and a parting strip corners, side walls 22 having longitudinally extending depressions 23 adjacent the base corners -20, and terminating in beads 24 spaced apart.

In the side walls of the groove I6 are formed longitudinally extending parallel recesses 25 spaced from the base of the groove.

These redust or the like at those points.

ICGSSGS are preferably at a fixed distance from the face of the rail I0 and thus determine the amount which the strip projects between the sashes. When the parting strip is seated in the groove, the base corners 20 enter the recesses 25 and thus the strip is supported thereby.

The sections of the parting strip are joined by pins or rods 26 which enter the beads 24, as shown in Fig. 3, sothat the sections act as a unit. The middle section I8 is located at the joinder of the closed sashes (see Fig. 1) and in it is mounted a block 21 of rubber or other resilient material which prevents the entry of wind, The pin or rods 26 may be merely at the joinder of the sections, as shown in Fig. 3, or may be extended through the beads 24, as shown in Fig. 6.

The parting strip bears against the sashes as shown in Fig. 5, the portions 28 of the side walls being held yieldably in contact therewith by the natural resiliency of the metal from which it is formed. The side walls of the strip are spaced at the depressions 23 from the walls of. the groove and thus the normal resiliency of the metal is not impaired. This contact, being over an appreciable area, serves tooffer a substantial barrier to the entry of wind, dust and the like and also holds the sashes against rattling.

The parting strip of this invention may be easily substituted for the usual wooden parting strip. After the recesses 25 have been formed in any well known manner in the walls of the groove t6, the sections of the parting strip are substituted for the removed wooden strip. A suitably formed tool (not shown) contracts the base of each section into the position shown in Fig. 4 and the section is then pushed into the groove until the base corners 20 register with the recesses 25 and the base resumes its normal position, as shown in Fig. 5. The three sections of the strip may be joined and the strip inserted in the groove as a unit, one or both the sashes having been removed, or the sections may be inserted seriatim and joined as they are inserted. The strip may be removed by a reversal of such treatment.

While one embodiment of this invention has been described and set forth in the drawing, it will be understood that the invention is not limited thereto and that other embodiments thereof may be made within the spirit and scope of this invention as set forth in the following claims.

I claim:

1. A parting strip adapted to be seated in the vertical groove of a window frame and to bear against the window sashes, which strip is substantially U-shaped in cross section and having rounded corners at the base, a rib projecting inwardly from the base, and inwardly projecting beads at the longitudinal edges of the side Walls, portions of the outer surfaces of the side walls adjacent the beads bearing against the window sashes, the beads being spaced apart at all times, and longitudinally extending depressions in the side walls between such portions thereof and the base corners, which depressions are at all times out of contact with the walls of the groove and said groove having longitudinally extending recesses in such walls which receive the rounded base corners of the strip.

2. A parting strip adapted to be seated in the vertical groove of a window frame having sliding sashes and to bear yieldably against such sashes, such strip consisting of a plurality of abutting sections, each section being substantially U- shaped in cross-section and having a base which rests in the groove, a rib projecting inwardly from said base, side walls extending from said base and including longitudinally extending depressions adjacent the corners of the base, and beads at the longitudinal edges of the side walls, portions of the side walls bearing against the sashes, the beads being spaced apart at all times, each groove having in its side walls longitudinally extending recesses which receive the rounded corners of the strip, means joining the abutting ends of each two adjacent sections, which means consist of pins in the beads of said strip sections, and yieldable means in the section at the meeting point of the sashes when closed which means seal the space between the beads thereof and prevent the entry of wind, dust and the like.

3. A parting strip adapted to be seated in the vertical groove of a window frame having sliding sashes and to bear yieldably against such sashes, said strip being substantially U-shaped in cross section and having a base which enters said groove, and side walls extending from said base and including longitudinally extending depressions adjacent the corners of the base, beads at the outer edges thereof which are in contact with the sashes at all times, the side walls of the groove being provided with longitudinally extending parallel recesses at a predetermined distance from the face of the frame rail, which recesses receive the corners of the base of the strip and thus determine the amount which the strip projects between the sashes.

4. A parting strip adapted to be seated in the vertical groove of a window frame having sliding sashes and to bear yieldably against such sashes, said strip being substantially U-shaped in cross section and having a base which enters said groove, and side walls extending from said base and including longitudinally extending depressions adja'cent the corners of the base, beads at the outer edges thereof. which are in contact with the sashes at all times, the side walls of the groove being provided with longitudinally extending parallel recesses at a predetermined distance from the face of the frame rail, which recesses receive the corners of the base of the strip and thus determine the amount which the strip projects between the sashes, and a rib projecting inwardly from the base midway between the corners thereof, the side walls of said rib being normally separated whereby upon contraction of the side walls the base corners of the strip are drawn toward each other so that the strip can be readily mounted in or removed from the groove.
